SPECIFICATION forming part of Letters Patent No. 358,117, dated February22, 1887.

Application filed September 25,1886. Serial No. 214,573. (No model.)

To all whom it may concern:-

Be it known that 1, JAMES HARRIS, a resident of Cincinnati, in thecounty of Hamilton and State of Ohio, have invented certain new anduseful Improvements in Stamping-Machines, of which the following is aspecification.

The primary object of my invention is to provide a machine for stampingsoap.

The various features of my invention and the advantages resulting fromtheir use, conjointly or otherwise, will be apparent from the followingdescription.

In the accompanying drawings, forming part I 5 of this specification,Figure 1 is a front elevation of my machine. Fig. 2 is a top view of mymachine. Fig. 3 is a perspective view of the carrier for delivering thesoap to the stamping-box. Fig. 4 is a perspective view showing anotherside of the carrier shown in Fig. 3. Fig. 5 is a perspective view of thecurved slide for receiving the bars of soap.

The machine is attached to a table, A,,snpported in any suitable manner.The bars of soap, cut to the proper size, are placed in the slide B, tobe fed to the machine. From the slide B they slip one by oneinto thecarrier D, which carries each bar separately to thestamping-box C, whereit rests on the platform E, 0 and is stamped by the plunger F. Afterbeing stamped the cake of soap is removed from the box by the fingers Gand dropped into a receiving-box.

The carrier D is a box partly open at two 3 5 sides and at the bottom.Near one end there is a cross-head, D, sliding in grooves d in the sidesof the box. To this cross-head the connectingrod D is attached and therod D The other end of the rod D is attached to the head H, which slidesbetween the top of the carrier D and the plate (I. The head H ispreferably made of two plates, h h, between which anumber of springs,h", are placed, forming a cushion. The head H is preferably providedwith a tongue to fit in a groove, cl, in the plate cl, to form therewitha guide for the head H. To the inner edge of the head Hthe cut-off H isattached.

The curved chute B is so placed that the series of bars of soap placedin it escape from its lower end onto the plate D, attached to the tableA. The chute B is provided with two chute both at the bottom and at thetop. These rollers are kept covered withvinegar, with between them. Thebox C projects above the table A, and has its sides open flush with thetop of the table.

The stamping block E fits in the box C. From the under part of the blockE the rod E projects downwardly, and has the arm Erig idly attached toit and projecting to. one side. The block E rests on the ends of thelevers E, which latter are supported and fulcrumed in hangers projectingdownwardly from the table A.

On the outer ends of the levers E are placed weights e, which may beadjusted on their respective levers to regulate the pressure supportingthe block E.- The cam I is rigidly attached to the shaft 1, the latterbeing supported in any convenient manner. The cani- I is locatedimmediately under the arm E The shaft J, journaled in standards K, isprovided with the tight or loose pulleys L. To

necting-rod, J connects the end of the crank J with the slide M, whichlatter moves vertically in guides, and to which the die or stamp holderF is attached.

On the top of the carrier D a device for dislodging the soap from thebox Cis placed. The lever N, fulcru med at N, has the weight n on oneend to keep it level. The weight at end of the lever N the block N isattached and fits in an opening in the top of the carrier. The rod 0passes through a guide, 0 and is attached to one end of the lever O, tothe other end of which the spiral spring 0 is attached. As the slide Mrises the tappet m strikes the lever O and lowers the rod 0. This latterstrikes against the end of the lever N and lowers the block N, which atthis part of the stroke is over the box 0. The box P moves in grooves inthe plate 1?. The box P is provided with an arm, 1?, which supports across-piece, P. A cross-head, R, fits in grooves 19 in the box P. Thecross-head R is operated by the connecting-rod R, attached to the crankR An arm, R is rigidly attached to the cross-head R and projects towardthe box C, carrying the cam r.

The arms G are rests on the top of the carrier. To the other or morerollers, I), set transversely across the which each bar of soap ismoistened as it passes its outer end is attached the crank J. Aconpivoted to the cross-piece I The arms G are provided with the fingersG. The other end of each of the arms G is provided with adownwardly-projecting finger, which fits in one of the grooves a" in thecam r.

The mechanism for imparting motion to the various parts of the machineis quite simple. A preferred form is shown in the drawings. Thedriving-shaft Jis provided with two beveled gears, which mesh withbeveled gears on the rods S, which by similar means transmit motion tothe shafts S S. The rod S, by means of beveled gears, transmits motionto the shaft 1.

The mode of operation is as follows: A series of cakes of soap ready tobe stamped are placed in the holder B, the weight of the pile forcingone of them onto the plate I)*. As the machine moves, the plate Hpresses the cake between itself and the end of the carrier D, thecut-off H at the same time being moved across the opening of thedelivery-chute B, to hold back the rest of the soap. When the crossheadD reaches the end of the slots in the carrier D, the whole carrier ismoved forward. At the end of the stroke the carrier is over the openingof the box 0, and as soon as the head H begins to return, the cake isreleased and drops into the box 0. XVhen the cake is inclined to stick,the downward movement of the block N, which occurs at this time,facilitates its passage into the box C. The carrier now returns to theposit-ion shown in Fig. 1 and receives another cake of soap. In themeantime the cake which has dropped into the bOX O has rested on theplate E and been stamped by the downward stroke of the stamp F. As soonas the cake of soap has been stamped, and while the stamp F is on theupstroke, the cam I lifts the plate E by lifting the arm E and bringsthe cake of soap on a level with the fingers G, which at this momentcome forward, open, grasp the cake, retreat, open, and drop the cake.

The mode of operation of the mechanism for operating the fingers G isquite simple. As the connecting-rod It moves forward it first moves thecross-head R, which, moving the camrforward, opens the fingers G.Continued movement of the cross-head R moves the box P and carries thefingersforward to a position over the box 0 where they surround the cakeof soap. The fingers G now grasp the cake and hold it a moment until theplate E has cleared itself. On the back movement of the connecting-rodIt the cross-head is first moved, drawing with it the cam, closing thefingers onto the cake of soap. The whole box 1 is now withdrawn, and atthe same time the fingers G are opened by the movement of the cam r andthe cake of soap dropped into a receiver. A feature of considerableadvantage in the machine is the cushioning of the head H, which allowsfor variation in the sizes of different bars, and still secures astronghold upon each bar.
